A Cleveland, Tenn., man was killed Tuesday night in a one-vehicle crash on the Oak Ridge Turnpike/state Highway 95 near Imperium Drive at the Horizon Center.

Police reports said 33-year-old Benjamin Park Birdwell died in the 7:30 p.m. crash. His body was taken to Roane Medical Center in Harriman.

Reports said the accident victim wasn’t properly restrained and was ejected from his 2004 Toyota Sienna van when the van left the road and rolled several times.

Birdwell reportedly was ejected through a side window.

Though reports indicated Birdwell may have been drinking, the police reports did not indicate alcohol was a factor in Tuesday’s crash. Blood tests are mandatory in a fatal wreck.

Birdwell was the sole occupant in the van and was driving east toward Oak Ridge when the van crashed. He was negotiating a curve when the van left the road. After it rolled several times, the van landed on its wheels in the median.
